If you import `cppyy` before ROOT, you get these warnings by default:
```txt
/home/rembserj/code/root/root_install/lib/root/cppyy_backend/loader.py:147: UserWarning: No precompiled header available (cannot import name 'get_cppversion' from 'cppyy_backend._get_cppflags' (/home/rembserj/code/root/root_install/lib/root/cppyy_backend/_get_cppflags.py)); this may impact performance.
warnings.warn('No precompiled header available (%s); this may impact performance.' % msg)
/home/rembserj/code/root/root_install/lib/root/cppyy/__init__.py:378: UserWarning: CPyCppyy API not found (tried: /nix/store/8w718rm43x7z73xhw9d6vh8s4snrq67h-python3-3.12.10/include/site/python3.12); set CPPYY_API_PATH envar to the 'CPyCppyy' API directory to fix
warnings.warn("CPyCppyy API not found (tried: %s); "
```
Doing the import locally, so it happens after `import ROOT`, avoids
these warnings.
